1996 I30t with 170k Poor low idle, stall when starting

[tdb332002]

Novice here, automotively speaking, and my first post. This board appears to be the best thing I've encountered, so here goes:

1. When starting my vehicle(in Maine-issue #1!), won't hold the start initially without manually giving it some fuel via accellerator.
2. Never has shifted great out of one and 2. Unresponsive. Seems to be empty power and definitely a delayed reaction and drops to 1000 rpm or under when foot removed from accelerator. When it descends, it may have an intermittent hesitation.
3. Now seems to vibrate and be a little loud as speed increases, most noticably at 65-70.

Recent maintenance includes: brand new battery, transmission oil changed and new filter. I have had a coolant sensor replaced in the last 6 mos.

Any clues at all? I appreciate in advance any help. Take care.

Basic maintenance: plugs, air/fuel filters first, for ALL connectors:

Throttle Pos sensor (100$) replacement or cleanup. (=if cold engine plus tranny problems)

Injectors might be problem (1000$)? All Sensors testing may be done after plug swap, connectors cleanup: KS, MAF, O2 and cam pos sensors.

It has similar sensors as maxima, in different places, check:

See for manual at bottom of page 1.


3a. Exhaust leak?. 3b. Tire pressure, wear, adj, thread broken, smtg loose, balljoints bad etc. Go for a checkup.

Btw. Dont let anybody fool you with MAF (expen$ive) or other spares, most can be tested. Tell them I'll check that later - I will, dunno when... If stealer$hip/anybody changes that, demand any old spares with you, some instant experts need 'em for emselves... then you throw away.

Thanks I appreciate your response. I will certainly examine or use as a starting list. Again, thanks.

Located after air filter, measures air mass [flowspeed]
