It started running rough and now won't run more than 5-10 mph. It seems to have a dead spot in the throttle and have changed the TPS sensor even though ALL sensors are reading good. It cranks and idles a little rough and it seems to only get gas at idle and at full throttle. Any suggestions?

Do you have check engine light??
ReplyDCH, April 05, 2014, 11:44Rookie
No check engine light and ALL sensor read good! I have heard some talk of the "Power Reduction" light or button cause similiar problems....but, I really don't know what to try next.

Have a mechanic to unbolt the cat converter see if it makes a difference
Something is clogged on your exhaust system
ReplyDCH, April 05, 2014, 12:08Rookie
Have already done that. The converter is not clogged.

What's the psi?
ReplyDCH, April 05, 2014, 12:52Rookie
Not sure. My mechanic did it last week....said all where good. Only has 112,000 miles on it. Enigine was in great shape when I purchased it a few months ago. My mechanic checked it out before I purchased it. So far, we have ruled out, blown gaskets, converter, TPS sensor, cracked block....etc.

What about do a fuel pressure test?
ReplyDCH, April 05, 2014, 13:33Rookie
Dropped tank, blew out the fuel lines, replace fuel filters and verified fuel pump pressure. Lmao....been there....done that. I'm at an impasse.
